    Brightness Not Adjustable, NVIDIA Driver

    I'm running 10.04 on my new Thinkpad T510 along with the proprietary NVIDIA driver. Brightness controls no longer work at all. The buttons are recognized and the adjustment notification shows correctly, but the screen brightness does not change.

    This worked fine initially when running the Nouveau driver.

    Anyone come across a similar problem?

    This has been a problem for a long time but can be solved by installing a package called nvclock.

    Then in System -> Preferences -> Keyboard Shortcuts
    click add
    set name to brightness-up
    and command to:
    Code:
    nvclock -S +5
    click add
    set name to brightness-down
    and command to:
    Code:
    nvclock -S -5
    then set keyboard shortcuts for the commands.

    Thanks, this is my first NVIDIA-based laptop so I wasn't aware it was an existing problem.

    I'll give your suggestion a try.

    edit: nvclock does not work on my card. A search on the web seems to indicate that it doesn't support newer cards and that this is a universal problem. I'll keep looking.
